Who’s behind the platform?

The Decidim Free Software Association is a democratic association for the governance of the Decidim community.
Som Energia (uusiutuvan energian käyttöä ajava osuuskunta) on luonut Decidimin avulla yhteisöllisen ja ystävällisen tavan osallistumiselle. Julkaisimme alustan vuonna 2018, jolloin alustan avulla pidettiin osuuskunnan yleiskokous ja kuukausia myöhemmin debatoimme osuuskunnan ylläpitämän koulun visuaalisesta uudelleensuunnittelusta ja yhteisöllisestä kehittämisestä muiden osallistumisprosessien lisäksi. Muutaman kuukauden aikana alustalle oli rekisteröitynyt yli 3 500 osallistujaa ja siellä oli viisi osallistumistilaa, kolme ryhmää ja sen kautta saatiin yli 1 300 ääntä yleiskokouksen äänestyksessä.

Olemme ratkaisseet lähes kaikki toteuttamamme osallistumisprosessit Decidimin toiminnallisuuden avulla. Työkaluna se on erittäin vahva, mutta sen vahvimmat ja meille tärkeimmät osa-alueet tuntuvat olevan sen ympärille kehittyvä yhteisö, niin alustan kehittäjien kuin sen käyttäjien osalta. Olemalla osana tätä yhteisöä, olemme oppineet arvostamaan yhteisöä ja sen kykyä ratkaista niitä haasteita, jotka liittyvät osallistuvan demokratian toteuttamiseen oikeassa maailmassa.

Part of what makes Decidim so powerful is that it adds a level of abstraction to the work separating out the steps of a process and the activities associated with the process. That’s part of the information architecture, so that not only you are saying what is happening at each step but different parts of Decidim behave differently depending on when you are doing or depending on what step in the process you are in. The fact that that’s customizable really allows Decidim to be moulded to how we are doing our work and not our work to be moulded.
